## Description

Advantage II Kitten is a vet-recommended, leading brand in cat flea protection. Advantage II Kitten flea treatment and prevention kills adult fleas, flea larvae and flea eggs to deliver total flea protection to your kitten. Within 12 hours of application, Advantage II Kitten topical treatment gets straight to work killing fleas through contact, so they don’t have to bite your kitten to die. This treatment works hard for 30 days following application, effectively breaking the flea life cycle, controlling existing flea infestations and preventing further infestations all month long. Fleas not only cause discomfort; they can also pose other risks. Monthly use of Advantage II Kitten is important to protect your kitten against fleas that may cause transmission of tapeworms, Flea Allergy Dermatitis and flea bite anemia. That’s why Advantage II Kitten makes applying treatment simple. This convenient, topical, spot-on application goes on the back of your kitten’s neck at the base of the skull. You’ll simply place the tip of the tube on the skin and squeeze the tube to expel the entire contents directly on the skin. It goes on in seconds! It's easier than a flea collar and there are no hard-to-swallow pills. You’ll also love that Advantage II Kitten is fragrance-free and waterproof after 24 hours of application. Check the product label for information on application and potential side effects. Advantage II Kitten flea protection is effective on both indoor and outdoor cats. Your kitten should be at least 8 weeks old and weigh between 2 and 5 lbs. to use Advantage II Kitten. For the ultimate convenience in care, Advantage II Kitten is available over the counter – no prescription needed. And, you can stock up with a subscription for regular doorstep deliveries so you never miss a monthly treatment. Advantage II Kitten is a trademark of Elanco or its affiliates.

Review: Although it is not 100% perfect to eliminate the pesky flees with their brood, it does provide sufficient amount of control over the pest population. It is one of best flea killing products on the market (I tried a few of them).
Review: i don’t normally write reviews but this was amazing! i have two full time inside cats both weighing about 9lbs each and an indoor free roam bun about 6 lbs. this product worked PERFECTLY my bunny. no side effects and fast acting. needless to say one of my cats escaped, went on a short stroll in the yard and decided to bring a flea back home. i used one capstar pill per cat in between this topical treatment and within 12 hours i took a flea brush to them all and they were flea free ! i had been searching the internet all weekend for something rabbit safe, and unfortunately, there isn’t much. his vet recommended a HALF pill in between this kitten topical treatment (his dosage based on his great health and weight of 6 lbs) and i couldn’t be happier with the outcome. for all the bunny parents struggling to find the answer or simply can’t afford a vet visit, i would recommend this and the capstar oral treatment. well worth the money and ease of the huge headache fleas bring. my babies are comfortable again and no longer itching.

### ⭐⭐⭐⭐⭐ Review
*by A***L on 18 May 2025*

I rescue a lot of kittens in my neighborhood. This last bunch had a flea infestation I’ve never witnessed before. I gave them all a bath in Dawn, to try to get rid of some of them, but I can’t bath them everyday because they are outside right now. They will be adopted. I’m just over run inside my house with community strays to get adopted. I applied this on the kittens at 7 weeks old even though they were a little under the 2lb limit. I had to stop the fleas!! This worked amazingly! No more fleas. I prefer to purchase on-line because it’s over the counter and getting flea medicine at the vet is so expensive. This works and I’m very particular on the kittens being so small and fragile. Don’t hesitate to purchase this product to get rid of fleas on kittens.
